The highway arbiter needs to be programmed such that
the SPDO unit’s latency requirement can always be met.
Refer to
tency can be computed as indicated below.
Given an output data rate f
are required each sample interval. The arbiter should be
set to have a latency so that the buffer is refilled before a
sample interval expires. See
practical settings.
